| Summary: | 碩士 === 中臺科技大學 === 環境與安全衛生工程系碩士班 === 103 === Taiwan is a global petrochemical products important producer, polymerization of the resin industry development starting in 1949, a petrochemical company produces phenol formaldehyde resin, the application is quite extensive for consumer goods, resin polymerization process is extensively used in the world, Taiwan also is one of them. Different products were quickly and diversified development, not fully understanding the chemical properties before which was applied in process, and triggered related disasters in chemical plant in Taiwan, due to the out of control, leading to injuries and property losses. Therefore, we used thermal analysis techniques to understand the process , for reducing the risk of disasters. Thermal analysis techniques used in this study for analysing the phenol formaldehyde resin, Differential scanning calorie metery, DSC) was applied in this study with heating rates of 2, 4, 6 ℃/min and three different mixing ratio and pH of the experiment to separately assess the impact at different process conditions. From the experimental results, when the phenol formaldehyde greater than its reaction heat ΔH had been significantly increased, and when the phenolic resin in the acidic conditions of pH which had significantly increased the reaction heat ΔH, decentralized heat in alkaline conditions, the situation in advance of the onset temperature T0 was occur. Simulation of thermodynamic parameters obtained based on experiments, safety parameters and test results can be applied to industris for reducing the risk of disasters.
